A couple DirectWave questions.

I'm making some percussion kits with DirectWave (not using FPC due to its 32 pad limitation). I've run into a couple issues here that I'm not sure how to solve.

1. Is there a way to prevent zones from cutting themselves? Some cases this is desirable but in many instances I'd like to overlap specific percussive sounds and not have them cut eachother off.
2. Can I a specific zone's sample through drag-drop? Dragging a wave from the browser to DirectWave just creates a new zone, it doesn't *replace* no matter where I drag it.
3. Is there a way to set a mixer offset similar to FPC so that I can add outbound effects to different zones (in my instance, percussive samples)?

Thank you very much to anyone for any assistance.
